Developed in 1983 by AATCC Committee RR90 (Revised 2018)

 

1.  Purpose and Scope

 

1.1  This test method provides a laboratory procedure for:

1.1.1  Determining the effectiveness of chelating agents in disperse dyebaths for inactivating heavy metals which can cause shade change.

1.1.2  Evaluating the sensitivity of disperse dyes to metal induced shade change during dyeing.

 

2.  Principle

 

2.1  The effectiveness of chelating agents in sequestering metals in a dyebath, thereby preventing metal-induced shade change, is determined by the protocol in Fig. 1.

2.2  Metal sensitivity of disperse dyes is determined by comparing control dyes and test dyes by a shown protocol.
